Change is very, very difficult for humans. As biological beings, we are bound by homeostasis. If an aspect of our being goes out of whack, our system will do its best trying to bring it back into balance. To use a very simple example, if our internal temperature deviates a degree or less, we shiver or sweat. Two or three degrees, we’re sick. Three or more degrees and we’re in danger of dying. According to our most basic nature, change does not correlate to survival. Fundamentally, despite our best intentions, we avoid it.

Look at habits. Look at the excruciating headaches that ensue from giving up caffeine, the emotional turmoil of quitting smoking, or the sometimes life-threatening symptoms of alcohol or opiate withdrawal. Once our body gets used to something, reversing the process sends it into a confused and urgent attempt to find equilibrium. Very often this involves pain.

Inconveniently, by this same principle, establishing new habits is as hard as breaking old ones. Always, always our system is trying to pull us back to what we’re used to – what it perceives as “safe.”

All this is to say, of course, that it’s very possible your body or psyche might be experiencing some disturb as you take up Aikido. This is not just common, it’s inevitable. Aikido is one of the most transformational practices there is because it blatantly requires us to shed layers and layers of the armor we’ve always used to survive, of who we’ve always taken ourselves to be. This is the only way to encounter our genuine, powerful, divine, authentic selves.

Not only that, Aikido insists upon doing this at a purely physical level. Processing and theorizing don’t help much. We just have to do it. Often we can’t explain the growth that is happening—to our selves or anyone else.

Faced with this level of threat, our homeostatic lizard brain will no doubt be on alert. This shows up in lots of ways: backing away from practice being the most common one I see. Whatever reasons we have for retreating can feel very real—needs suddenly materialize in other areas of our life, demanding our time and attention at the exact times we’ve planned to be at the dojo. Our protector parts can be very clever.

Starting Aikido isn’t like quitting smoking or taking up jogging or leaving a toxic relationship or changing our diet—obviously healthy decisions that everyone can understand and get behind, that after some months of discomfort lead more or less to a permanent shift. No, this is a spiral inward, ever deeper into ourselves to uncover endless new territory. And some aspect of our system will always be fighting like hell to make sure that change doesn’t happen. Each moment of transformation comes with some psychological or emotional or physical disruption—sometimes fun and mind-blowing, other times uncomfortable and painful. It’s a commitment like no other, it grows us like nothing else, and we have to be very, very brave to take it up and keep it up. We have to be warriors.

As I write this, I’m nursing an uncommon injury resulting from one of these all-to-common transformational moments: a badly taken fall resulting from (what else?) resistance. It’s brought up an inexplicable sadness; and a mysterious fear lurks, black and smokey, at the edge of my consciousness.

I recognize this as an inner valve twisted open to release some new layer of my soul that’s ready to emerge. Of course, that hasn’t stopped my mind from doing its cursory flip through the catalogue of ways to make the pain go away: give up, retreat, find an alternative, blame, keep resisting… Fortunately I’ve been at this long enough that this list breezes through in a matter of seconds, dusted atop the solid knowing that the only thing to do is get back on the mat in a few days. Slow my movements way down. Get support in practicing, practicing, practicing this particular thing to loosen my resistance around it. Get a reality check from Sensei on the dimensions of the issue that I know I’m blind to.

Generally, it’s important to remember that if we’re uncomfortable it probably means we’re growing. Trying to fix the discomfort by going back to an old way of being is not the action of a warrior. Plus it rarely works. Instead, welcome the discomfort. Get curious about it. Lean into it, explore it. What old part of you is being challenged? How and why is it fighting? What’s getting ready to shift? (The best place to check this out, of course, is in the dojo. Sure, journal about it all you want, but make sure to get your uncomfortable self back on the mat.)

And remember that everyone who chooses the path of warriorship is going through this on some level. In any given moment someone on the mat is on the brink or in the midst of a change that homeostasis is trying to talk them out of making. The serenity you see in the faces of more advanced practitioners is from having gone through this millions of times and knowing it’s going to happen again—and thankful for it, because each instance makes us bigger, opens us further, releases us deeper. Scary and inexorable. Sublime in its mystery.

Have compassion for yourself and your companions who are making the hard decision every day to challenge the allure of homeostasis and change for the better—and make a better world for us all.
